Description
The HCPL-4100 optocoupler is
designed to operate as a transmit-
ter in equipment using the 20 mA
current loop. 20 mA current loop
systems conventionally signal a
logic high state by transmitting
20 mA of loop current (MARK),
and signal a logic low state by
allowing no more than a few
milliamperes of loop current
(SPACE). Optical coupling of the
signal from the logic input to the
20 mA current loop breaks
ground loops and provides very
high immunity to common mode
interference.
The HCPL-4100 data input is
compatible with LSTTL, TTL, or
CMOS logic gates. The input
integrated circuit drives a GaAsP
LED. The light emitted by the
LED is sensed by a second inte-
grated circuit that allows 20 mA
to pass with a voltage drop of less
than 2.7 volts when no light is
emitted and allows less than 2 mA
to pass when light is emitted. The
transmitter output is capable of
withstanding 27 volts. The input
integrated circuit provides a
controlled amount of LED drive
current and takes into account
any LED light output degrada-
tion. The internal shield allows a
guaranteed 1000 V/
μ
s common
mode transient immunity.
CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to
prevent damage and/or degradation which may be induced by ESD.
